Delay-coordinate reconstruction and conditional-moment causal diagnostics in stochastic systems

Jun Ohkubo · 2026

Partial observation and delay-coordinate reconstruction are rooted in deterministic dynamical-systems theory, whereas there are many systems with intrinsic stochasticity. We propose a conditional-moment interpretation of delay-coordinate reconstruction for stochastic systems, in which a delay vector is used to reconstr …

Neuron merging via inverse-activation regression for post-training compression of sigmoid neural networks

Ao Kuniya, Jun Ohkubo · 2026

As neural networks continue to grow in scale, model compression is becoming increasingly important for efficient inference under limited computational resources. Structured pruning methods remove neurons or channels that are estimated to be less important, but the removed units may still contain useful information. Fro …
